Google search from Excel

In Excel 2007, is there a way to add a button to a tool bar that will perform a Google search on the selected cell? Alternatively, is it possible to add Google search to the "Research" function (Review, Proofing, Research, Research options list)? Or for that matter, could another button be added for another type of search, eg IMDB?

Not sure if this is what you're after, but might be worth checking out this add-in for MSOffice:

You can have it set for IMDB or any other site as well as the Microsoft Knowledge Base.
